GREASE-CUP.

Application filed May 16. 1918.

To all whom it may concern:

Be it known that I, OLAF BAKKE, a citizen of the United States, residingat New England, in the county of I-Iettinger and State of North Dakota,have invented certain new and} useful Improvements in Grease-Cups, ofwhich the following is'a specification- This invention relates toimprovements in grease cups, and more particularly to that type adaptedfor feeding grease or other lubricants of a thick character and in whichthe cup is formed of two parts having threaded engagement with eachother to provide for applying pressure to the lubricant to insure thefeed thereof to the bearing to which the cup is connected.

In connecting grease cups of this character to bearings and especiallyto bearings of automobiles which are subjected to considerablevibration, the parts work loose and become lost or cease to exertpressure on the lubricant, and it is to overcome this objection that thedevice constituting this invention is devised.

Another ob ect is .to provide a grease cup which may be as easilyadjusted as the ordinary cup and when adjusted, the'movable part may beeasily locked in adjusted position by a simple locking device carried bythe cup cap.

WVith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the'preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 represents a side elevation of agrease cup constructed in accordance with v this invention with the capshown in locked position thereon,

Fig. 2 is a similar view taken in a plane at rinht angles to Fig. 1 withthe cap shown slightly unscrewed, and

Fig. 3 is a plan view showing the locking element in operative position.

In the embodiment illustrated, a grease cup 1 is shown provided at oneend with the ordinary threaded stem 2 for connection with the bearingand is externally Specification of Letters Patent.

threaded on its upper enlarged end as shown at 3 to receive aninternally threaded cup cap 4; whichis adapted to hold the lubricant andto be screwed downwardly ,on the body portion to force the lubricantout.

The cap 4- is provided on its cup with a pair of laterally spaced lugs 5which incline downwardly in opposite directions gradually merging intothe cap and preferably being formed integral therewith. By soconstructing these lugs the locking element presently to be describedmay easily ride up on either one of them and be dropped between them inthe sear. formed by their opposed ends. 7

This cap 4: is provided on one side wall with laterally extendingvertically spaced and alined bearing ears 6 which are designed toreceive an L-shaped locking member "his locking member 7 is composed ofheavy spring wire and the terminal or free end of the arm which extendsthrough the bearing 6 is bent at an oblique angle to form a finger 10which when in operative position is designed to engage the face of thecup proper as shown clearly in Figs. 1 and 2. The short arm 8 of themember 7 is extended horizontally and adapted to swing over the upperface of the cup of cap 4, the lugs 5 on said cap being arranged in thepath of said arm so that when the arm reaches the space or seat betweenthese lugs it will drop thereinto and thus lock the cap to the cup as isshown clearly in Fig. 1. The free end of arm 8 has its terminal bent toform a loop 9 designed as a handle for operating the locking element.

In use, the cup is filled in the ordinary manner and the cap t is turnedon the stem portion to exert the pressure on the lubricant. When thedesired pressure has been obtained, the locking member 7 is turned inthe bearing 6 by grasping the handle 9 which causes the arm 8 to swingover the top of cap 4 and to ride up on one of the in clined lugs 5until it reaches the highest point thereof which is adjacent the spacebetween the lugs and when said arm passes over this end, it will dropinto the seat formed between the lugs and owing to its resiliency willclosely hug the top of the cap and be held by the lugs against turningin either direction until it has been manually released from thisposition. When this arm is so locked the finger 10 will have grippingengagement with the inclined face of the body proper 1 as shown in Fig.1, thus exerting a clamping action on the cap and holding it securelyagainst turning onthe body portion of the cup. The foregoing descriptionand the drawings have reference to hat may be considered the preferredor approved form of my invention. It is to be understood that I may makesuch changes in construction and arrangement and combination of parts,materials, dimensions, etc., as may prove expedient and fall Withinthe'scope of the claimed invention. p 7

Having thus fully described my invention, What I claim as new and desireto secureby Letters'Patent is j 1, A. grease cup comprising a fixedmember, a 'r'otat able cap movable onthe fixed member, and rotatablemeans carried by said cap for engaging th fixed member to lock thecapagainst rotation. v x "2. A grease cup comprising a fixed menr her, acap rotatable thereon, a rotatable rod carried by said cap, and means onsaid rod for clampingly connecting the cap to "the cup. r a

A grease cup comprising a fixed member, 'acap rotatable thereon, andhaving' laterally extending vertically spaced and ali'nedi bearings, anL-shaped locking member having'on'e arn mount'ed on said bearings withits free end extending below the bot tom of the cap and shaped to engagethe cup of'said member in operative position.
